I have a few different Loctite two part adhesives in cartridges with a dispenser. I tried gluing two pieces of nylon together. I'm using EA E-30CL which is supposed to bond plastic. I applied the adhesive and clamped the two pieces together. I waited over 48 hours before I unclamped them. I was easily able to break the two pieces apart. I was also able to easily scrape off the adhesive with a razor blade. What did I do wrong?
I didn't do anything special to prepare the surface. I wiped it down with 99% Isopropol. I just read the literature on that adhesive and it said it needs pockets (I forget the wording) for the adhesive to sit in. Should I score the surfaces?
I would also like to start bonding aluminum with adhesive. I figure if they can glue cars together I can glue some metal together. What kind surface prep and adhesive is strongest for aluminum?
